[0001] This utility model relates to the technical field of wearable bracelets, and in particular to a crystal bracelet with a hidden NFC antenna. Background Technology

[0002] With the development of smart technology, people's functional needs for everyday items are increasing. Traditional crystal bracelets, as a common type of jewelry, only have a decorative function. However, NFC (Near Field Communication) technology, due to its convenience, is widely used in access control, payment, information storage, and other fields.

[0003] Currently, there are few products that integrate NFC technology into crystal bracelets, and existing technology has many problems:

[0004] Some attempts have been made to embed the NFC antenna directly into the crystal bead, but the high hardness and brittleness of the crystal make the processing difficult and the antenna easily damaged.

[0005] The dielectric properties of crystal can severely attenuate NFC signals, resulting in insufficient signal strength and affecting the performance.

[0006] Existing integration methods often affect the appearance of the bracelet, failing to maintain the original beauty of the crystal bracelet, and lack structural design that facilitates maintenance and replacement of NFC components.

[0007] In view of this, the inventor has designed a crystal bracelet with a hidden NFC antenna, which leads to this invention. Utility Model Content

[0038] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0039] Please see Figures 1 to 8 This is a crystal bracelet with a hidden NFC antenna, which is the preferred embodiment of the present invention. It includes several crystal beads 100, a string 200, a support 300, and an NFC tag 400. The string 200 passes sequentially through through holes 110 provided on the crystal beads 100 and the support 300, connecting the various parts in series to form a closed loop. Details are as follows:

[0040] First, such as Figure 3 , 4 As shown, the support 300 includes a split-type upper cover 500 and a lower base 600.

[0041] Specifically, in this embodiment, the top cover 500 is a rigid structure. The top of the top cover 500 is a hemispherical arc surface, and its overall shape is curved. The corners form arc transition angles. A tag fixing groove 510 matching the NFC tag 400 chip is opened at the center of the bottom of the top cover 500. The NFC tag 400 chip is embedded in the tag fixing groove 510. A pair of hooks 520 are formed on both sides of the bottom of the top cover 500 along its length extension direction and at its center. The bottom of the hooks 520 has a snap-fit ​​protrusion 521. The snap-fit ​​protrusions 521 on the two hooks 520 extend in a direction away from each other.

[0042] In this embodiment, in order to facilitate connection with the lower seat 600, the design position of the hook 520 is a certain distance from the bottom edge of the upper cover 500, that is, it is recessed by a certain distance, so as to facilitate connection with the lower seat 600 and hide it inside the lower seat 600, so that the entire support 300 forms a complete whole.

[0043] In this embodiment, the top cover 500 is an integrally bent structure made of polycarbonate. Polycarbonate has a low dielectric constant, which can minimize interference with the signal of the NFC tag 400.

[0044] like Figure 3 , 4 As shown, the lower base 600 consists of a soft base layer 610 located on the lower side and a rigid connecting layer 620 embedded on the upper side of the soft base layer 610. The top of the rigid connecting layer 620 is provided with a slot 621 that engages with the hook 520.

[0045] In this embodiment, both the rigid connecting layer 620 and the flexible base layer 610 are curved to form a shape that adapts to the upper cover 500, making it easy to connect and install with the upper cover 500.

[0046] Specifically, the rigid connecting layer 620 is a shell structure with an internal cavity 622 and an open bottom. The upper end of the flexible base layer 610 is provided with a positioning part 611 that fits into the cavity 622. Thus, the rigid connecting layer 620 is inserted into the flexible base layer 610 from the upper side of the positioning part 611, so that the positioning part 611 is embedded in the cavity 622 of the rigid connecting layer 620, thereby realizing the connection and fixation between the rigid connecting layer 620 and the flexible base layer 610.

[0047] Preferred, such as Figure 4 , 5 As shown, the rigid connecting layer 620 has symmetrically arranged clearance holes 623 on its upper surface and along its length, which are connected to the cavity 622 and used to accommodate the hooks 520. The slots 621 are symmetrically arranged at the bottom of the side walls on both sides along the length of the rigid connecting layer 620 and are connected to the inner cavity and the external environment. Thus, through the design of the clearance holes 623, when the top cover 500 is inserted downward into the rigid connecting layer 620, the hooks 520 on both sides can enter the cavity 622 along the clearance holes 623 and then move downward along the cavity 622 to the position of the slots 621 at the bottom of the side wall of the cavity 622. Finally, the latching protrusion 521 of the hook 520 is limited to the latch 520 in the slot 621, fixing the top cover 500 to the rigid connecting layer 620. The relatively hard rigid connecting layer 620 achieves a stable connection with the top cover 500, avoiding problems such as deformation and loosening caused by connecting with the top cover 500 through a soft part.

[0048] Preferred, such as Figure 4 , 5 As shown in Figure 6, the bottom of the sidewall of the rigid connecting layer 620 protrudes towards the inside of the cavity 622 to form a limiting edge 624, and the bottom of the positioning part 611 is recessed inward to form a limiting groove 612 that fits into the limiting edge 624. In this embodiment, the limiting edge 624 extends vertically inward from the bottom of the sidewall of the rigid connecting layer 620 and is continuously distributed around the bottom of the four sidewalls of the entire rigid connecting layer 620 to form a closed rectangular shape. When the rigid connecting layer 620 is inserted downward from the upper side of the flexible base layer 610, the deformation of the flexible base layer 610 allows the limiting edge 624 to move downward along the sidewall of the positioning part 611 and finally fit into the limiting groove 612, thus completing the connection and fixation between the rigid connecting layer 620 and the flexible base layer 610 and further increasing the stability of the connection between the two.

[0049] Preferred, such as Figure 4 , 6As shown, the positioning part 611 is recessed inward on both sides along its length to form a relief groove 613 that is opposite to the relief hole 623 and the slot 621 and is used to allow the hook 520 to move. The outer side and top side of the relief groove 613 are directly connected to the external environment. The relief groove 613 is located at the center of the side wall of the positioning part 611, which is exactly opposite to the position of the hook 520 and the relief hole 623. The size of the relief groove 613 allows the hook 520 to move fully, avoiding affecting the limiting and matching process of the hook 520 and the slot 621.

[0050] Preferred, such as Figure 3 , 4 As shown, a flexible pad 700 is provided between the lower base 600 and the upper cover 500. The flexible pad 700 is fitted into the label fixing groove 510 to cooperate with the lower base 600 to compress and fix the NFC tag 400. The flexible pad 700 has a porous sponge structure. Thus, through the flexible pad 700, the NFC tag 400 can be fully compressed and confined within the label fixing groove 510, thereby further enhancing the stability of the NFC tag 400.

[0051] Preferred, such as Figure 7 , 8 As shown, two through holes 110 are provided along any one of the crystal beads 100 and the lower seat 600, and two corresponding wires 200 are provided, which are distributed horizontally on both sides of the crystal beads 100 and the lower seat 600. The side wall of the rigid connecting layer 620 is recessed upward along its bottom to form two positioning ports 625 for accommodating the wires 200. The positioning ports 625 penetrate the side wall of the rigid connecting layer 620 and connect the cavity 622 and the external environment. The two positioning ports 625 are distributed on the left and right sides of the slot 621, and the lower side of the positioning ports 625 extends to its bottom, thus forming a structure with a lower opening. During the installation process, after the wires 200 pass through the two through holes 110 of the flexible base layer 610, the rigid connecting layer 620 is pressed downward to fix it on the upper side of the flexible base layer 610. During this process, the lower opening of the positioning port 625 will accommodate the wires 200 to avoid affecting the installation process of the rigid connecting layer 620.

[0052] Preferably, the soft base layer 610 is a medical-grade silicone layer, and the rigid connecting layer 620 is a polytetrafluoroethylene layer.

[0053] In this embodiment, the NFC tag 400 is a passive NFC tag 400.

[0054] The beneficial effects of this utility model are as follows:

[0055] This utility model uses a support 300 to replace the crystal bead 100 for the hidden installation of the NFC tag 400, avoiding the complicated processing of the crystal bead 100 and the interference of the crystal bead 100 on the NFC signal. At the same time, through the split design, the rigid part supports the NFC tag 400, while the soft part contacts the human skin, which can not only achieve the purpose of convenient maintenance and replacement, but also achieve a good user experience.

[0056] Among them, the lower base 600 rigid connecting layer 620 made of polytetrafluoroethylene and the upper cover 500 made of polycarbonate have low dielectric constants, reducing the attenuation of NFC signals.

[0057] In addition, the split support structure 300 has an upper cover 500 connected to the lower base 600 via a hook. During maintenance, the upper cover 500 can be separated simply by pressing the outer slope of the hook engagement protrusion 521 from the outside of the opening of the slot 621, which facilitates the replacement of NFC tag chips. The soft base layer 610 of the lower base 600 can be disassembled and cleaned separately, which improves the maintainability of the product.

[0058] Furthermore, the hemispherical arc design of the top cover 500 and the bottom of the base 600 makes the surface of the bracelet smooth, coordinating with the appearance of the crystal beads 100 and maintaining the beauty of the crystal bracelet. The soft medical-grade silicone base 600 conforms to the wrist, improving wearing comfort.

[0059] In addition, the double string 200 enhances the stability of the string 200 connection, ensuring that the bracelet is not prone to tilting or loosening during daily use.

[0060] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
